- SPECIFICATION forming part ef Letters Patent No. 701,562, dared June s, 1902.

Application filed October 29, 1901. Serial No. 80,409. (No model-3 To @ZZ whom it' may concern:

Be it known that I, HENRY S. HALE, of the city and county ofPhiladelphia,State of Pennsylvania, have invented an Improvement in Car-Seats, of which the following is a specification.

My invention has reference to car-seats; and it consists of certain improvements, all of which are fully set forth in the following specification, and shown inthe accompanying drawings,'which forma part` thereof.

The object of my' invention is to provide a suitable construction of carseat cushion combining metal and textile material which shall be strong and at the same time very lexible or yielding, whereby it has great sustaining qualities coupled with softness and comfort to the occupant in use.

In carrying out my invention I provide a Wooden frame with a series of sheet-metal spring-plates sustained upon coil-springs and over Which the textile padding and covering is placed. The spring-plates are built up ini compound construction-that is to say, they are each comprised of a series of long parallel plates connected at intervals by short transverse plates, the central long plate when employed being preferably wider than the outerl plates and directly supported upon the coilsprings and the connectionwith `said springsl b'eing desirably formed by bolts or rivets passing through the cross and long central plates and' ends of the coil-springs. The ends of the long parallel plates :may be bentdown-g ward and secured to the"Woodenfrarneandl the textile covering is placed overthe series of metal spring-plates and secured to the wooden frame of the seat.

My invention alsol embodies detailsof con-` struction, all of which will be better understood by reference to the drawings, in which- Figure is a plan view of a car-seat embodying lmy invention and having the padding and covering removed and part of the under textile covering' turnedback to exposerthe spring structure. Fig.p2 is a cross-section of same with the upholstery in place. Fig. 3 is an enlarged transverse sectional View through oneof the spring-plates and top of the coil- 5o spring, and Fig. Il is a side view of one of the long spring-plates removed.

A is the wooden frame and consists 'of the side and end rails and a series of cross-bars F at the bottom. The side rails of the wooden frame A are longitudinally grooved on the Vupper edge, as at B, and are adapted to receive the ends of the spring-plates. These springplate structures extend across the Wooden frame at intervals in its length and constitute a metallic support for the padding,` .They each consist of a wide central metal plate C and two side plates C' C', set close to it, .but preferably without contact. :The ends C2 of these plates are 1curved downward and secured inthe grooves Bl of the woodenv frame by nails or otherwise. The three plates C' C C' are connected by three cross-plates D, which are riveted thereto 'at e and e. The

' wider central plates C are secured by the rivets c also to the upper ends of the coilsprings E, as shown in Figs. 2 and 3. This construction gives great elasticity and ilexibility, but at the same time it maintains sufficient strength to sustain great weight. By the use of the side strips C the space between two adjacent plates C is lled in, and

'this yis accomplished without making the plates Cso abnormally wide as to destroy the vuniversal elasticity required in said plate. `vMoreover, the transverse 'plates I greatly strengthen rtheHsprir'Ig-plate structure as a whole without interfering with its elasticity,

so necessary in a seat of this construction.

Above the spring-plate structures I arrange Atextile Webbingof sufficient width as to overlapth'ef lateral 6rv outer Iedges of the 'so as to shield the upper textile covering against cutting or abrading action. These webbing-pieces are shown at F and are riv- A ret,ed in place by the three rivets e, passing through. the central plate C. They are not plates,

secured to the side plates C', because it is not necessary to hold them in position, and, secondly, it is preferable to leave the vsaid plates free on account of securing more 'lexibiltyx G is a sheet or cover of textile `materialcovering all of thesprings-andfis secureiil tothe Wooden frame. Above Vthis is placed the padding H, and over said paddin'gi's ai covering of upholstery J. The padding may be omitted, if desired.

While I prefer the construction shown, I

IDO

do not limit myself to the minor details thereof, as they may be modified without departing from the spirit of the invention.

The strips C C' may be smooth or corrugated, as indicated in Fig. 4 at c, said corrugations being at intervals in the length of the plate. While all three plates of the spring-.plate structure may be corrugated, if desired, the corrugatious may be put upon the central plate C alone. The object of the corrugations is to give additional strength transversely to the length of the plate, and thus enable a thinner plate to be used than is otherwise suitable. While I prefer the central plate C wider than the side plates C', it is evident that all of these plates may be of the same or any suitable width.

Vhile I have shown the use of three springstrips C C' C for each spring-plate structure, it is evident that more than three strips may be secured together in the manner shown, or, if desired, the central strip C may be omitted and the springs E connected only with the cross-strips D, to which the strips C' C' are connected. It is further evident that, broadly considered, it is not necessary that the ends of the strips C C' C' shall be directly fastened upon the side rails of the frame A, since they will be retained in their position by the upper webbing.

While I prefer the construction shown, I do not limitmyself to the details, as these may be varied without departing from the spirit of my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a seat-cushion the combination of a wooden frame, a series of spring-plate structures extending across the top of said frame and each comprising a series of parallel strips connected together by cross strips, coilsprings secured to the cross-strips and supported within the wooden frame, and suitable upholstery arranged above the spring-plate structure and secured to the wooden frame.
